35mm Piezoelectric Sensor without Wire Electronic Kits This is convenient for makers35mm Piezoelectric Sensor without Wire A piezoelectric transducer converts mechanical force into electrical output. When the force is applied to stretch or bend it, an electric voltage is generated. If there is no stress, no charges are induced. When there is stress, positive charges are induced on one side and negative charges are induced on the opposite side. Compression occurs in the crystal as the force is applied.
